Title: Continuous electrolytic water preparation device
Inventor: OKAZAKI TATSUO
IPC: C02F1/46
Filed: 1991-12-21
Abstract: PURPOSE:To make it possible to select between various types of electrolyzed water such as obtained at normal temperature or by cooling or heating so that the flow rate ratio of alkali water and acid water can always be made constant by providing a bypass circuit which detours a heat exchanger and fixing the flow rate ratio of a downstream alkali drainage tubular path and a downstream acid water tubular path as specified. CONSTITUTION:Water flowing through an alkali water drain tubular path 6 is selectively switched to either a tubular path 6a running through a heat exchanger 9 or a tubular path 6b detouring the exchanger 9 by changing over a switching valve 8. Consequently, alkali water at normal temperature and cooled or heated alkali water can be selectively taken out of an intake faucet 10. Further, a flow balancing valve 15 for maintaining the flow of the alkali water drain tubular path 6 and an acid water drain tubular path 7 in the downstream side of the heat exchanger, to a constant level, is installed at both tubular paths. Thus it is possible to maintain the flow of the drain tubular paths 6, 7 always to a specified ratio.

Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To provide a digital CMOS circuit whose threshold voltage can be controlled. SOLUTION: A voltage Vdd/2 is applied to a reference voltage input terminal 7. When an input terminal 5 receives 0 V, a PMOS transistor(TR) 10 is conductive and a voltage at an output terminal 6 is equal to a voltage of a 1st power supply Vdd. In this case, a switch 30 is open to shut off a current flowing from the 1st power supply 1 to a 2nd power supply 2. When the input terminal 5 receives a voltage of about Vdd/2, differential pair TRs 100, 200 compare the voltage at the input terminal 5 with a voltage at the reference voltage input terminal 7 to decide the share of the current. When the voltage at the input terminal 5 is a little than the Vdd/2, the voltage at the output terminal 6 is close to the Vdd, and when the voltage at the input terminal 5 is a little than the Vdd/2, the voltage at the output terminal 6 is close to 0 V.  When the voltage at the input terminal 5 is equal to the Vdd, an NMOS TR 20 is conductive and the voltage at the output terminal 6 is as low as a voltage of the 2nd power supply, that is, 0 V. In this case, a switch 40 is open to shut off a current flowing from the 1st power supply 1 to the 2nd power supply 2.

Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To take in and out an automobile, and to prevent falling of wheels from the placing part by arranging a fall preventive beam at a prescribed interval in front of the front wheel placing parts. SOLUTION: The front wheel placing parts 16 are arranged by two pieces in the front wheel support part 13 in response to left/right wheels by forming a main beam 11, a front wheel support beam 13 and rear wheel support beams 14 and 15. The rear wheel placing parts 17 are arranged by two pieces on the rear wheel support beams 14 and 15 in response to left/right wheels. A falling preventive beam 1 is arranged at a prescribed interval in front of the front wheel placing parts 16. When a rack violently vibrates, an automobile moves forward, so that front wheels fall in front of the front wheel placing parts 16. At this time, since the falling preventive beam 1 is arranged at a prescribed interval, the front wheels are prevented from moving more than that in the shape of sinking in clearance between the front wheel placing parts 16 and the falling preventive beam 1.  Therefore, falling of the automobile from the rack can be prevented without hindering taking in and out of the automobile.
